    Magnetic flux in the inter-network quiet Sun from comparison with numerical simulations
    Khomenko et al. estimate the mean magnetic field strength of the quiet Sun to be 20 G. The figure is smaller than several existing estimates, and it comes from...

    Magnetic flux in the internetwork quiet Sun
    We report a direct comparison of the amplitudes of Stokes spectra of the Fe i 630 nm and 1.56 μm lines produced by realistic MHD simulations with simultaneous...

    Magnetic Flux, Heating, & Flaring: Clues from the Sun for Other Stars & Systems
    On the Sun, the presence of magnetic flux at the photosphere is closely linked to (1) steady heating of the overlying atmosphere and (2) transient brightenings...

    Magnetic imaging of the outer solar atmosphere (MImOSA)
    The magnetic activity of the Sun directly impacts the Earth and human life. Likewise, other stars will have an impact on the habitability of planets orbiting...
